android 中 onsaveinstancestate()使用方法详解

覆盖onsaveinstancestate方法，并在oncreate中检测savedinstancestate和获取保存的值

@override 
protected void onsaveinstancestate(bundle outstate) {  
  outstate.putint("currentposition", videoview.getcurrentposition()); 
  super.onsaveinstancestate(outstate); 
} 

public void oncreate(bundle savedinstancestate) { 
  super.oncreate(savedinstancestate); 
  setcontentview(r.layout.main);  

  initview(); 

  if (savedinstancestate != null 
      && savedinstancestate.getint("currentposition") != 0) { 

    videoview.seekto(savedinstancestate.getint("currentposition")); 
  } 
}
